SPECIFICATION forming part of Letters Patent No. 717,622, dated January6, 1903.

Application tiled December l2, 1901. Serial No. 85,589. (.No model.)

To MEZ wtont t may concern/ .Be it known that l, MAncELLUs REID,residing at Providence, in the coun'tyof Providence and State of RhodeIsland, have in- '5 vented certain new and useful Improvements in Framesfor Tire-Drawing Machines, of which the following is a full, clear, andexact description such as will enable others skilled in the art to whichit appertains to make and io use the saine.

My invention relates to a frame for a wiredrawing machine; and itsobject is to provide a construction which shall be compact and of smallnumber of parts and especially adapted to withstand the varions strainsto which it is subjected in the operation of wire-drawing. I attain thisobject by the construction illustrated in the accompanying drawings, inVwhich- Y Figure lis a side elevation. Fig. 2 is an end elevation. Fig. 3is a top plan; Fig. 4, a transverse vertical section, and Fig. 5 alongitudinal horizontal section.

Throughout the drawings similar reference characters refer to similarparts.

The various members of myimproved frame are preferably of cast-iron,although they may be formed in any desired manner. The frame comprisestwo side members or uprights, each cast in one piece, as bestillustrated in Fig. 1, and having end uprights 1 l in the form ofangle-irons, base-pieces 2, center pieces 3, which are formed at theirupper and lower ends as lll-beams 4 4, connected by a web in the shapeof a 'T-beam 5. The upper ends of these side members are flanged or bentinwardly, as at 6, and rabbeted to provide seats for a top plate. Alower tie-piece connects the side members at their lower ends and isprovided with flanges which are connected to the tlanges ou the lowerI-beams 4 4 by bolts or otherwise. Tie-piece 'Z has formed therein ajournalbearing 8, adapted to provide a bearing for a horizontalline-shaft,fromv which power is supplied to drive the wire-drawing drum.A casting 9, bolted to the tie-piece 7, provides a cap for theline-shaft bearing and likewise a socket or step-bearing 10, adapted toreceive a vertical spindle on which the Wire-drawing ing-bolts can belocated in readily-accessible 6o position. Through lugs 13, extendingupwardly from web l1, additional securingbolts are passed for connectionwith the side members. Web ll carries, cast integrally therewith, asshown, an upwardly-extending sleeve 14, which furnishes an additionalbearing and guide member adapted to support the drum-spindle. The sidemembers are further bound rigidly together by cap or cover plate 15, theopposite sides of which 7o rest in the rabbeted seats 16 on the tops ofthe side members, being secured thereto by bolts which pass down throughthe coverplate' and the inwardlyprojecting danges of the side members.It will thus be seen that the side members are rigidly held together bythe two tie-pieces, and further bound together and likewise preventedfrom buckling inwardly understraiu by the cap-plate.

A large circular hole is out in the top of this 8o cap-plate, which isadapted when the wiredrawing block is assembled to jreceive the iiangeof theAdrawing-out drum, or, if desired, of the wire-drawing drum,thereby allowing said drum or drums to be brought into close proximityto the upper tie-piece. Holes 17 17 are provided on diagonally oppositecorners ol' the side members for the reception of pivot-pins for adie-box. Flange or drum 12 is extended at 1S to pro- 9c vide a bearingfor an auxiliary spindle used for, driving a drawing-out druinfrom theline-shaft. The sleeve 14, which is integral with or rigidly connectedto the upper tiepiece, and accordingly rigidly connected with 95. thewhole framework, extends well above the upper surface of the cap-plateand accordingly well above the point at which the strain upon thewiredrawing drum would normally come in operation. Thus a conroostruction is provided in which the strain of wire-drawing is absorbed bya sleeve rigidly connected with the framework instead of beingtransmitted, as in the usual construction, to the vertical shaft, whichcarries the drawing drum or drums. This, in connection with the specialstiffening construction described, forms an important part of myinvention, as it enables the strain upon the machine to be distributedevenly throughout the whole framework and to a great extent preventsbreaking down in use. Castings 19 19, bolted to the sides of the drum12, furnish bearings for a horizontal shaft adapted to be used as arock-shaft for throwing a clutch for starting the drum.

It has not been deemed necessary to illustrate all the parts of thewire-drawing block in the present application, as such illustrationwould only serve to obscure the invention which is claimed herein, whichis lilnited to the peculiar construction of framework. Such frame isspecially adapted to be used in connection with a wire-drawing blocksuch as'described in my application now pending, Serial No. 66,202,tiled June 27, 1901, which application discloses a construction offramework in some features similar to that of the present application.It will be understood, however, that I am not limited to the use of thisinvention in connection with the special block in the application abovenoted, inasmuch as it may be adapted with slight modiications to avariety of wire-drawing machines without altering its essentialcharacteristics.

Having described my invention, what I desire to secure by Letters Patentis- 1. A frame for a wire-drawing machine comprising 1two side members,upper and lower tie-pieces, the lower tie-piece being provided with abearing for a line-shaft, and a step-bearing for a vertical shaft theupper tie-piece being provided with an elongated bearing in alinementwith said step-bearing, whereby the transverse strain caused bywiredrawing operation is absorbed by said elongated bearing at a pointabove the normal line of draft of the machine, and a cap-platev cut outto encircle said sleeve and acting as a supplementary binding-piecebetween said side members.

2. A frame for a wire-drawing machine, comprising two side memberscomposed of upright end pieces 1, 1, on center piece 3, base and toppieces 2 and 6, tie-pieces 7 and 11 between said side members and havinganges adapted to be bolted to the flanges of said side members, bearing8 in connection with tie-piece 7, cap 9 therefor having socket 10therein, stiffening-drum 12 in connection with the tie-piece 11, andelongated sleeve 14 integral therewith, substantially as set forth andfor the purpose described.

8. A frame for a wire-drawing machine, comprising two side memberscomposed of the upright end pieces 1, 1, center piece 3, base, and toppieces 2 and G, tie-pieces 7 and 11 between said side members and havingflanges adapted to be bolted tothe flanges ot' said side members,bearing S in connection with tie-piece 7, cap-piece 9 therefor havingsocket 10 therein, stiffening-drum 12 in connection with tie-piece 11,and an elongated sleeve 14 integral therewith, and a cap-plate 15resting in rabbets in the side members and rigidly bolted thereto,substantially as and for the purposes set forth.

In testimony whereof I affix my signature in the presence Of twowitnesses.

MARCELLUS REID.
